Best AI tools for Copywriters

Every job, one table

Every job this work actually runs into, in the order it happens — each with our top reviewed pick. Jump to any row's reasoning below.

The picks, job by job

Why each pick wins its job — and the honest tradeoff it asks you to accept.

• Research the offer, the audience and the claims

  Perplexity★ 4.4Editorial score 4.4 out of 5Free plan available; from $16.67/month billed annually

  It comes back with the sources behind an answer, so you can read the review threads, the spec sheet and the competitor's own page — the raw material for copy is quotes and proof, not a summary.

  Tradeoff: It finds sources, it doesn't verify them. Citations mismatch often enough that any number you put in a headline needs checking against the primary source yourself.

• Find the angle and the outline

  ChatGPT★ 4.7Editorial score 4.7 out of 5Free plan available; from $8/month (Go), $20/month for Plus

  It's the better sparring partner for divergence: twenty objections, ten angles, five structures in one thread, and you can paste the product screenshot or the competitor's landing page straight in.

  Tradeoff: Quantity is not judgment. Most of what it produces is the obvious angle in different clothes — the job is still picking the one that's true.

• Draft the long-form copy

  Claude★ 4.7Editorial score 4.7 out of 5Free plan available; Pro from $17/month billed annually

  It holds a full brief, the voice guide and three research documents in one pass, so a 2,000-word page keeps the same argument and register at the end as at the top.

  Tradeoff: Its default prose is smooth and slightly over-written. Ask for the version with a third of the words removed, then write the first line yourself.

• Write headlines and hooks at volume

  ChatGPT★ 4.7Editorial score 4.7 out of 5Free plan available; from $8/month (Go), $20/month for Plus

  Short-form variation is a numbers game, and the fast iterative loop here suits generating forty subject lines and throwing away thirty-eight. Same subscription as the angle work.

  Tradeoff: It gravitates to the same rhythms — question, colon, benefit — so specify the constraint (length, no colons, one clause) or you'll get the same headline forty times.

  When the copy is scored on conversions: Anyword — Every variation carries a predicted performance score trained on conversion data, which is a different argument for a variant than a copywriter's taste.

• Rewrite copy that isn't yours

  Wordtune★ 3.9Editorial score 3.9 out of 5Free plan available; from $4.89/month billed annually

  Editing a client's draft is sentence-level work, and this gives you around ten ranked rewrites of the sentence you selected, with a formality dial — you pick, rather than accepting a wholesale rewrite.

  Tradeoff: English only, daily caps on the lower tiers, and AI21 publicly scaled back investment in 2025 — worth knowing before you build a process on it.

  Copy written in a second language: DeepL Write — Translation-grade fluency across six languages fixes prose that's correct but reads as translated, which no English-first rewriter does well.

• Proof the final deliverable

  Grammarly★ 4.5Editorial score 4.5 out of 5Free plan available; Pro from $12/month billed annually

  It runs in the document you're delivering from — Docs, Word, the CMS, the email — so the last pass happens where the typo would actually ship, not in a tab you pasted into.

  Tradeoff: Accept every suggestion and it will sand the character off a deliberately blunt line. Turn off the tone suggestions when the voice is the point.

• Hold a brand voice across a team · optional

  Jasper★ 4.2Editorial score 4.2 out of 5No free plan; from $59/month billed annually

  Trainable brand voice plus campaign workflows and governance is the reason an in-house team pays for it — output stays on-style across writers and channels.

  Tradeoff: $59/month billed annually and no free plan. For a solo writer with one client's voice in your head, this is a subscription you don't need.

• Write to an SEO brief · optional

  Surfer SEO★ 4.2Editorial score 4.2 out of 5No free plan; from $49/month billed annually

  The Content Score is the number clients and agencies actually put in the brief, and the editor scores you live inside Google Docs or WordPress while you write.

  Tradeoff: No free plan and no trial — a 7-day money-back guarantee — and hitting the score is not the same as being persuasive. Write the page, then optimise it.

  When you build the brief yourself: Frase — Compresses the SERP into a structured brief — headings, questions, coverage — in about a minute, which is the research half rather than the scoring half.

• Research keywords and competitors · optional

  Semrush★ 4.5Editorial score 4.5 out of 5Free plan available; from $117/month billed annually

  When you're pitching a content programme rather than writing one page, this is the data behind the argument — real volumes, intent and what the competitor already ranks for.

  Tradeoff: $117/month billed annually is agency money, and it now tracks AI-search visibility on higher tiers. Most freelance writers should have the client share their seat.

• Deliver in another language · optional

  DeepL Translator★ 4.5Editorial score 4.5 out of 5Free plan available; from $8.74/month billed annually

  For a client shipping the same page across markets, it keeps register and idiom closer to the original than a general assistant, which is the difference between localised copy and translated copy.

  Tradeoff: A translation still needs a native speaker's read before it goes live — nuance in a headline is exactly what survives least.

Skip these for copywriters

Good tools, wrong job. Each of these is reviewed in the directory — the reasons below are specific to this workflow, not verdicts on the tools.

• Copy.ai — The name still says copywriting, but the product moved to go-to-market automation — workflow credits, CRM enrichment, outbound sequences, priced for ops teams. Its workflow tiers start far above what a writer would pay, and a working copywriter gets nothing here that Claude or ChatGPT doesn't do better.
• Writesonic — An SEO-article and AI-search-visibility platform from $79/month billed annually, with per-article quotas. It's built to produce content at volume for a brand, not to write to a brief — and it competes with your job rather than helping you do it.
• Rytr — Genuinely cheap and genuinely limited: short-form templates with one tone of voice on the Unlimited plan. Fine for someone who writes occasionally, thin for someone whose output is the deliverable.
• QuillBot — A student's paraphraser. Rewriting to a brief means changing what the sentence argues, not changing its words — and running a client's copy through a spinner is how you end up delivering something you can't defend in a review.
• AdCreative.ai — Generates ad visuals scored for conversion from your brand kit. Useful to a performance marketer, but the deliverable is an image set, not copy — and its layouts are recognisable enough that clients notice.
• Sudowrite — A fiction workshop: it's built for scenes, character and description. Commercial briefs want the opposite discipline, and its strengths would actively hurt a landing page.

Frequently asked questions

What is the best AI tool for copywriting?

There isn't one — the jobs are different. Claude drafts long-form because it holds the whole brief at once; ChatGPT is the better variation engine for headlines and angles; Wordtune rewrites at sentence level when the copy isn't yours; Grammarly does the final pass. A working stack is roughly $59/month, and all four have free tiers.

Claude or ChatGPT for copywriting?

Claude for anything long: a sales page, an email sequence, a white paper — it keeps voice and argument consistent across thousands of words. ChatGPT for divergence and short form: angles, forty subject lines, and reacting to a screenshot you paste in. Most copywriters who use both use them exactly this way.

Will AI replace copywriters?

It has already replaced the part of the job that was volume — variations, first drafts, product descriptions at scale. What it doesn't do is decide what's true about the offer, choose the angle that matters to this audience, or defend a line in a client review. The writers losing work are the ones who were selling words rather than judgment.

How do I make AI copy sound like my brand voice?

Feed it evidence rather than adjectives. Three pieces of your best existing copy, the customer's own phrasing from calls or reviews, and an explicit list of what you never say beats any instruction like "be witty but professional". For a team that needs this repeatable across writers, Jasper's trainable brand voice is what you're actually paying for.

Do clients know if copy is AI-written?

Some ask, and some run detectors — which are unreliable enough that they'll flag human writing too. Agree it up front: most clients care that the copy is accurate, on-brand and yours to stand behind, not which tools were open while you wrote it. Where a contract requires disclosure, disclose.

Is Surfer SEO or Frase better for writing to a brief?

Surfer if someone else sets the target: the Content Score is the number agencies put in contracts, and it scores you live in Google Docs. Frase if you're building the brief yourself — it compresses the SERP into headings and questions in about a minute, and it's cheaper with API access on every plan. Neither makes the copy persuasive; that's still your job.
